Map Projection for Small Areas

Jan 31, 2012 at 2:24 PM

Hi Everyone,

I am working in small areas like 100x100 meters for a school assingment. I want to use a plain cartesian coordinate system and also, I want the unit distance 1 meter (distance between X=0 and X=1) in order to use measurement tool. I guess these kind of projection can't be selected. 

When I don't select any map projection in code, "Invalid or Missing Projection" pop-up appears and ask me to select a projection type whenever I start my application. If I choose unmodified coordinates I can get what I want, but I don't want to do it everytime. I am studying electronics and not familiar with geographical sciences, so I don't know how to set geographical properties. I will appreciate if I can find any solution to this problem. 

Thank you...
